REGULATOR DEVICE Russian patent published in 2000 - IPC

FIELD: heat supply systems. SUBSTANCE: regulator device designed for heat supply systems with cascade lift has pumping equipment of heat generator, pumping equipment inlet and outlet lines. return line connecting upper level heat consumer with pumping equipment, and regulator connected to pressure pipeline between pumping equipment and heat consumer inlet. Regulator has hydraulic turbine with fixed guide vane assembly and flow rate control valve mounted behind hydraulic turbine in direction of heat carrier flow, simular regulator being installed in return line. Invention provides possibility of partial return of work used for overcoming piezometric head in straight pipeline and work taken for building pressure differential in straight pipeline and at heat consumer instruments. EFFECT: saving of work. 1 dwg
